Laparoscopic colorectal resections with and without routine mechanical bowel preparation: A comparative study.

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• The necessity of mechanical bowel preparation (MBP) prior to laparoscopic colorectal surgery is debated.
• Evidence regarding the impact of omitting MBP on surgical outcomes is limited.

Purpose of the Study:

• To evaluate the safety and efficacy of omitting mechanical bowel preparation (MBP) in patients undergoing laparoscopic colorectal resections.
• To compare surgical outcomes between patients who underwent MBP and those who did not.

Main Methods:

• A retrospective cohort study comparing patients who underwent elective colorectal resections without MBP to a historical cohort with MBP.
• Analysis of outcomes including operative time, estimated blood loss, anastomotic leakage, wound infection, surgical morbidity, and conversion rates.

Main Results:

• No significant differences were observed in operative time, estimated blood loss, anastomotic leakage rates (1.0% vs 0.6%), wound infection rates (4.1% vs 3.8%), or overall surgical morbidity (11.3% vs 8.2%) between the No-MBP and MBP groups.
• Conversion rates were also similar between the groups (5.2% vs 6.9%).

Conclusions:

• Omission of mechanical bowel preparation (MBP) is a safe practice for patients undergoing laparoscopic colorectal resections.
• Eliminating MBP does not adversely affect key surgical outcomes such as operating time, conversion rates, or complication rates.
